Wait

  • It belongs to the ‘Object’ class.

  • This method releases the lock when synchronization is in process.

  • It is to be called only from a synchronized context.

  • This method has three overloaded methods, namely

    • wait()

    • wait(long timeout)

    • wait(long timeout, int nanoseconds)

Sleep

  • It belongs to the ‘Thread’ class.

  • It doesn’t release the lock on the object when synchronization is in process.

  • It is a static method.
